Historical water data

The following excel files provide historical Available Water Determinations (referred to as allocation announcements under the Water Act 1912) for all regulated river water sources.

Pre-water sharing plan announcements have been compiled in a single excel file.

From the commencement of the relevant water sharing plan for each regulated water source, an individual excel file is provided, where data for each water year is listed in separate worksheets.

Available Water Determinations for the current water year are available from Water allocations.
